How many Ahs do you really need?

Actually the charger part of the inverter/charger is much more robust than your average RV converter. Neal is right here. I think the disconnect is a result of not having experience with DP systems and quality inverter/chargers.

You are calling your convertor a charger, that is all. Terminology.

Actually that is not the case at all. As with many (perhaps most) , I have an inverter with a built in battery charger, not a converter, hence the term inverter/charger. I suppose you could call it a converter because its making 12v DC out of 120v AC, but it is not at all similar to common RV converters. Converters provide a source of 12v DC from 120v AC to those functions requiring 12v DC. The “charger” portion of the inverter/ charger is a battery charger that charges the battery bank, while the battery bank is the source of the 12v DC for the functions needing that energy source. Its more than semantics - it is quite simply a different type of equipment.

So my 1st through 4th trailer/RVs had converters. Well till the converter failed in the 95 MH. I replaced it with 3 stage smart converter/charger.

I and @TheLooks have tried to tell y'all that it is just a choice of words to no avail! Anyway I decided to search articles on the topic so that someone other than an unrespected certified RV technician might offer insight on the topic!!! Before I put down the link though, I have a question! How many low voltage cables are connected to your converter/charger?

I got an answer to the lead question to this one. I am going to be replacing the batteries on my coach. 2019 Duch Star 4018. I currently have 8 6v HB 210 Ah batteries in place. I have a MS2812 Magnum Inverter/charge. If I understand the math that is 420 Ah available (840x 50%). I am seriously considering one 280 Ah 12v SOK battery. Now before anyone pulls the arrows out, I think we are a little wierd. We have power in our storage facility and rarely boondock. When we do (at a motorcross track or rodeo facilities), there will be scores of trailers running generators through the night. We don't have any plans in the near or mid term to do any "real" boondocking like many on here seem to. If our mission changes or I determine that the one is completely inadequate, I can easily add one or possibly two of these same batteries. My 4018 is pretty heavy on the front end so If I can get away with the one, I can knock just short of 600# off my front end. Has anyone else tried this? If yes, how did it go?
